In this study, the HBAs from 23 of LOFAR’s core stations were used, providing a maximum baseline of \(\sim \) 3.5 km. Raw visibility data were produced using LOFAR’s interferometric mode for 253 baselines, providing a temporal resolution of 1s and spectral resolution of 12.207 kHz [1]}. Observations were taken for a number of subbands, every 10 MHz between 120 MHz and 180 MHz, and integrated over 5.5 seconds in order to increase signal-to-noise. The angular resolution of the 23 station array ranges from 2.0 at 120 MHz and 1.2 at 180 MHz. In the following analysis, the data from the core stations were used to produce interferometric maps and carry out the lunar de-occultation technique.
